Application filed. December 13, 1913.

b all whom it may concern Be it known that l, ALoNzo E. Rnonnns, acitizen of the United States, and resident of llopedalc, county ofWorcester, State of ll'fassachusetts, have invented an Improve: ment inFilling-Slackencrs for Looms, of which the following description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawing representing like parts. A

In looms provided with automatic filling replenishing mechanism theseveral filling carriers are mounted ready for use in a suitable hopperor feeder from which they are transferred singly to the lay as required.The filling ends from the several filling carriers have to be securelyheld as the filling carrier is transferred. to the lay and beaten acrossthe loom. The sharp blow of the picker on the freshly supplied shuttlesubjeets the filling end to such a shock that it frequently breaksbefore the filling begins the unwinding from the end of the fillingcarrier. Consequently, various means have been devised to overcome thisdifficulty.

The present invention presents an improved means for providing slack inthe filling end when required. This is secured in the present inventionby not merely releasing or pern'iitting slack in thesgifilline end butby positively slackening up the filling end. In the preferred form ofthe invention this positive lackening of the end is secured by providingan individlnil end holder for each filling end and giving to it upon thetransfer of ts filling carrier a positive movement to carry the end heldby it toward the filling carrier, and thus positively slack-en thefilling end.

It is essential in this character of device that the filling ends shallnot be left loose, but shall be held taut up to the time of the transferof the filling carrier, otherwise they are liable to be caught in themechanisin of the loom or entangled with the other filling ends. This isprovided for in the present invention by the individual end holders andby providing for their actua tion through connections with the transfermechanism itself so that the slackening of a filling end is controlledby or through the transfer of its filling carrier from the hopper. Theseand other features of the invention will appear more fully from theaccompanying description and drawings, and

will be particularly pointed out in the claims.

The drawings represent only so much of the mechanism of a loo-1n as isnecessary to a disclosure of the present invent-ion, and the mechanismilhilstrated, and to which an embodiment of this invention is shown asapplied, is that of the well known Northrop type of loom.

lln the drawings: Figure 1 is a front clevation and partial section of afilling feeder and adjacent port-ion of the loom together with the partsembodying my invention; Fig. 2 is an end elevation of the parts shown inFig. 1, without a repetition of some of the parts which are the same foreach filling carrier; Fig. 3 is a detailed view showing in a sectiontransverse to the axis of the filling feeder the means for mounting andpivoting the individual end holder.

Reference may be had to my prior Patent No. 1,059,638 granted April 22,1913 for the general type of filling feeder and connected parts hereinillustrated, and as the general construction of the filling feeder andthe construction and operation of the means for transferring afilling-carrier therefrom to the shuttle in the lay upon the call forfilling replenishment are well known and familiar they need not be heredescribed in detail.

The filling feeder 'or hopper comprises the circular plate 1 withbutt-receiving pockets and having its hub 2 mounted to rotate on thehorizontal stud 3 fixed in the hopper stand 1- carried by the loomframe. The outer feeder plate 5 is provided with a hub 6 rigidly mountedon the hub 2, and at its periphery is shown as provided with tipholders7 all as shown in my prior patent.

.lnstead of the usual disk and stud for holding the filling ends andproviding slack, this invention provides an individual holder for eachfilling end positively moved to slacken positively the end upon thetransfer of its filling carrier from the hopper or feeder. In theconstruction illustrated the shaft 3 is extended to the right and.connected by a bracket 8 with the usual transferrer shaft 9 which isalso extended to the right for that purpose.

The reduced portion 10 of tl e hub 2 upon which the outer feeder plateis mounted is extended to the end of the shaft A shouldered hub 11provided with an enlarged annular rim 12 is mounted on the portion 10 ofthe hub 2, abuts against the outer feeder plate 5 and is held in placeby a set screw 13. An annular seat 14 is mounted on the hub 11 abuttingagainst the shoulder thereof, and is held in place by an annularretainer 15 also mounted on the hub 11 and secured thereto by a setscrew 16. This seat and retainer constitute the pivotal support for theindividual end holders.

The individual end holders are shown as arms each of the sameconstruction, one being provided for each filling end. Each arm 17 isformed at its outer end with suitable means for gripping the fillingend. In

the construction illustrated the filling is brought over the end of thearm and wound about a projection 18 thereon. These rms 17 are preferablyflat or are flattened at their lower ends and fit within the peripheralradial slots 19 of the annular seat 15. The seat is grooved at itsperiphery circum ferentially to form open bearings for the pivot pins 20of the arms 17. The annular retainer 15 is provided adjacent the seatwith an annular projecting flange 21 fitting over the periphery of theseat 14 and slotted at 22 to correspond with the slots 19, thus holdingthe pivot pins 20 in their bearings. The annular retainer 15 is alsoextended radially at 23 to form astop limiting the swinging movement ofthe arms 17 toward the filling carriers.

The parts thus described present a simple construction and one which maybe readily manufactured and assembled. The slots may be readily cutinthe seat and retainer. The seat is then slipped on over the hub 11 andagainstthe shoulder. The pivot pins 20 are placed in the arms, the armsdrop in the slots 19 bringing the pivot pins, into the open bearings,the annular retainer is slid on over the hub until it abuts against theseat with its slots in radial alinement with the slots of the seat, thusholding the pivots in their bearings. The set screw 16 is then set upand the hub 11 then carries all the parts and may be slipped on over thehub 10 and locked in place by the set screw 13. The other parts to bedescribed connected with the arms are, of course, placed in positionbefore the assembling takes place.

Each arm or individual end holder 17 is providedwith a detent by whichit is held in position to maintain the filling end taut. These detentsare shown as pawls 24 pivoted at 25, and limited in their movementtoward the center by stop pins 26 on the arms. The detents are normallyprojected toward the center by coiled springs 27 abutting thereagainstand pocketed in seats 28 secured to or formed integrally with the arms.The annular rim 12 is beveled or cam-shaped at 29 on theportion of itsperiphery toward the arms and the end of the detents is correspondinglycam-shaped or beveled at 30 so that when the detents are freefrom theannular rim and the arms are swung away from the filling carriers thedetents by reason of the cooperating cam surfaces 29 and 30 will slideup and snap over and lock upon the annular rim.

Means are provided for positively moving each arm or individual endholder toward the filling carrier, and for this purpose coiled springs31 are pocketed inthe hub 11 and abut against projections 32 at the baseof the arm 17.

The arms 17 if not in outward position are thrown over by the operativeagainst the spring 29, the detent 24 rides over and catches upon theannular rim 12 and then the operative inserts the filling carrier 33 inthe seats in the feeder and carries the filling end over the tip holder,draws it taut andsecures it to the free end of the arm 17 This is donewith each filling carrier and its filling end. If now the detent 24 bereleased from the annular rim 12 the corresponding individual end holderor arm 17 will be moved by the spring 31 to carry its free end towardits filling carrier, thus positively forming slack in the run 34 of thefilling end, as shown at 35. In the present invention this movement ofthe individual end holder is controlled by or through the transfer ofits corresponding filling carrier from the hopper, and as hereinillustrated, by mechanism operated from the transferring device itself.A striker lever 36 is fulcrumed at 37 in a hub formed in the bracket 8and has its free end 38 bent in and project ing radially within the pathof the ends of the detents 24. The opposite end 39 of the striker leveris provided with a pin 40 riding in a slot 41 of one arm of a lever orconnection 42 mounted on the transferrer shaft 9 and connected to theusual transferrer arm. 'Hence when the transferrer arm is moved upon thecall for filling replenishment and acts to transfer the filling carrierfrom the hopper the striker lever is I moved to release thecorresponding detent 24, thus causing the actuation of the correspondingfilling end holder and positive slackening of the corresponding fillingend.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:
